Hi WinTOTO User,
Many test has been done to ensure Assemblix software will work in the new windows operating system Windows Vista.

WinTOTO Standard, Advance, 2004 all can run in Windows Vista with faster processing power.

However, when you trying to register or upgrade the program, you may need to do some changes to the Windows security features. The installed directory must be set to allow user read/write control, otherwise, you cannot upgrade or register the software.
